The 4WRL10W80S-3X/G24Z4/M proportional solenoid valve belongs to the 4WRL Solenoid Valves series from Bosch Rexroth and is intended for precise hydraulic automation where fast, repeatable spool positioning is needed. It operates on a 24 V DC supply, and the coil has a resistance of 2.5 Ω at 20 °C, so the solenoid draws up to 2.7 A while consuming a peak of 40 VA during steady-state energization. A response time of 25 ms for a 0–100 % stroke shift at a pilot pressure of 100 bar supports rapid control loops, and hysteresis does not exceed 0.1 %, keeping position error minimal. The valve accepts pilot oil through a dedicated circuit that requires at least 10 bar and delivers 4 l/min to the control stage. Electrical interfacing follows the DIN 43560-AM2 line socket standard and mates with a DIN 43650 / ISO 4400 connector sized M16 × 1.5.
The main stage passes hydraulic flow up to 170 l/min while maintaining stable modulation across the spool range. Port groups p, A, and B tolerate pressures to 350 bar, whereas ports t, X, and Y are limited to 250 bar; the same 250 bar figure applies to the pilot supply’s maximum rating. An IP65 housing shields the internal electronics and moving parts against dust ingress and low-pressure water jets, making the valve suitable for exposed machine frames. All dynamic seals are manufactured from NBR to ensure compatibility with common mineral-oil fluids and to retain flexibility across typical operating temperatures.
